How Google Took on Mirai, KrebsOnSecurity

February 3, 2017

The third week of September 2016 was a dark and stormy one for KrebsOnSecurity. Wave after wave of huge denial-of-service attacks flooded this site, forcing me to pull the plug on it until I could secure protection from further assault.

Alas, the inaugural entry for Ne’er-Do-Well News looks at three recent unrelated developments: The availability of remote access iPhone apps written by a programmer perhaps best known for developing crimeware; the return to prison of a young hacker who earned notoriety after simultaneously hacking Paris Hilton’s cell phone and data broker LexisNexis; and the release of Pavel Vrublevsky from a Russian prison more than a year before his sentence was to expire.

The events of the past week reminded me of a privacy topic I’ve been meaning to revisit: That voice-over-IP telephony service Skype constantly exposes your Internet address to the entire world, and that there are now numerous free and commercial tools that can be used to link Skype user account names to numeric Internet addresses.
